If it's ok with Lorby, I started making videos on how to use Axis and Ohs in MSFS2024. I have time this summer to create a playlist of items - and as I build my own cockpits my plan is to cover doing things like connecting Arduinos and all of that. I'm done with MSFS for binding and use AAO for everything, so my content covers getting the full plane put into AAO - at least as I've experienced it.

• (https://youtu.be/dm19ALfaPUk) This is an introduction to the kinds of events and variables that you will need to know about in Microsoft Flight Simulator 2024 in order to use Axis and Oh's to connect your hardware to the sim.
• (https://youtu.be/teeP5hUvJjU) This is an overview of how to bind and tweak an axis using Axis and Ohs in Microsoft Flight Simulator 2024. We will do basic axis in a Cessna 152, split throttle in Beechcraft Starship, thrust reversers in Learjet 35A, non-flight controls, and finally multiple control surfaces with one axis in the Pilatus PC-12. The last example I'll go into more detail in the next video as we need to talk about scripting a bit.

(https://youtu.be/3A7u2ym8rzQ) New one covering Templates, Buttons, and Toggle Switches: By the end, you'll have the Diamond DA40 flyable and can use it as a model for binding other basic planes. We'll start this discussion with how to create and use templates so we can save time and get a plane up and running faster using our previous work. Then I cover switches considering the value of toggle and set along with standard events versus B variables. Then we learn 3 ways to do repeating commands with pitch trim. We learn how to combine actions into a single button press with the master engine switch. Finally, we cover how to use logic to bounce something between two states using a single button.

 

I've only watched one video so far, but I wish you'd have made these years ago. Learned more in the video than constantly referring to the manual.

This post should be a sticky to keep it on the 1st page. New users of AAO should find these videos invaluable as I did.

Thanks for the kind words. Next video is up.

(https://youtu.be/5Q4wuM_Qua4)This tutorial goes over the process of connecting an ESP32 and using an Arduino project to create a custom display altimeter that uses Axis and Ohs to get information from Microsoft Flight Simulator 2024. The altimeter has altitude, barometric pressure, an altitude bug, and I discuss how you can bind buttons in Axis and Ohs to change the pressure and altimeter bug.

Great videos! Wish these had been around a few years back. I did find however in the Starship trims, the Rudder Left and Right works better without the up event. I was getting strange behavior with the Right Trim interpreting the Up event as a turn to the Left after the Right down event had executed. When I removed the Up event, behavior was as I expected. The left trim did not do this, but I removed the Up event anyway. Hope this helps...

Thanks for the feedback - it's sometimes hard to know if those "down" and "up" LVARS are needed or not, so I tried to mirror what I saw in the dev mode.  Now that you bring it up on another plane I noticed I didn't need the up event, so I will note it for an addendum on that one.

I just uploaded a video on how to interface Axis and Ohs with DCS. Using AAO has allowed me to make my Arduino (well ESP32) driven screens and physical inputs (LeoBodnar) interact with DCS and MSFS without having to use different code on those devices.
